configure.ac: stronger test for pthread linkageew/autoconf-pthread
We need to test linkage of pthread_create and pthread_join, as pthread_mutex_* and pthread_key_* functions do not need extra linkage under FreeBSD 10.3, leading to a false-positive of the empty case. Signed-off-by: Eric Wong <e@80x24.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
